Off to drop off the first batch of shipments.

Also, good learning experience. Paypal deducts their fees from the invoice due amounts, so they nibbled away some… Well whatever… Account for it in the future.

Was this because this batch was personal stock not your shop your building?

These units are a part of my company’s production batch. I just wasn’t familiar how Paypal worked with their fees when using their invoicing system, so my fault I suppose. My Paypal account is a personal one, so I’ll check what benefits there would be to update it to a business account.

XT30 vs XT60

XT30 rated for 15A continues Flexi BMS rated for a 8A charge Current down side is XT30 only take a AWG18 cable 0.82mm2 and my fuse holders have bigger cable.
With the XT double the width I’m thinking little tails are my best bet

Would it be possible to run multiple of these in series for a 20s pack?

You won’t be able to use CAN-communication, but it could be done if you only use them to independently charge them as two series 10S packs. You can’t connect the single charger to both packs at the same time though, so you’ll either need to charge them one-at-a-time or use two floating output chargers to charge both packs at the same time. AKA, charging wise, handle them as two independent packs.

@SimosMCmuffin this changed from 10A?

Nope, don’t know where that 8A rating has come from, maybe some older HW version, but current HW from 0.4 forward officially supports up to 10 Amps charging current.
